Application filed August 25, 1922.

T 0 all whom it may concern.

Be it known that I, AUGUST ConcELL, a citizen of the United States.residing at Pittsburgh, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inSafety Devices for Windows, of which the following is a specification.

This invention relates to a safety device for windows, and the primaryobject of the invention is to provide a safety device of the characterdescribed, in a manner as herein after set forth, which is adapted to bepermanently fixed to the Window frame to provide full protection topersons working at the outside of the window for cleaning the same orfor any other purposes, particularly when such windows are positioned atsome height from the ground.

Further important objects of the invention are to provide a safetydevice of the type stated, which may be readily attached to a windowframe of any construction without the use of any special materialsexcept those embodied in the invention itself, which is simple in itsconstruction and arrange ment, strong, durable and efficient in its use,collapsible when not in use, and comparatively inexpensive tomanufacture.

With the foregoing and other objects in view, which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the preciseembodiment of the inventlon herein disclosed can be made within thescope of what is claimed without departing from the spirit of theinvention.

In the drawing forming a portion of this specification and wherein likenumerals of reference designate corresponding parts throughout theseveral views Figure 1 is a erspective view of a window having myimproved safety device attached thereto.

Figure 2 is a fragmentary vertical view of the inner face of a windowframe illustrating the attachment of the supporting brackets and theplatform.

Figure 3 is an enlarged perspective view of the supporting bracket.

Figure 4 illustrates the platform and guard in the folded position.

Referring in detail to the drawing 1 and 2 denote. respectively, theupper and lower Serial No. 584,273.

sashes of a window of the ordinary construction. The sashes are mountedin the usual window frame including the respective vertipal side members4 and 5 and the window si 1 6.

Fixedly secured to the inner face of each of the vertical side members 4and 5, by means of the countersunk screws 7, is a forwardly projectingsupporting bracket 8, substantially triangular in contour. The brackets8 on respective side members 4 and 5 are disposed in parallelismrelatively to each other.

The lower end of each of the brackets 8 is turned inwardly to form agroove 9 which extends along the entire lower edge of each of thebrackets 8 with the exception of the rear portion 10. The latter extendsbelow the oove 9 on the an even vertical plane and is provided withapertures 11 for the reception of the securing screws 7.

The inner face of the rear portion 10 of each of the brackets 8 isslightly depressed relatively to the plane of the inner face 12 of theprojecting portion of the bracket 8, for the purpose to he described.

A substantially U-shaped guard rail 13 has the end of each its armspivotally connected to the rear portion 10, of a respective bracket 8, bmeans of the screw 14, which latter exten s through the aperture 15provided therefor in each of the brackets 8. As the rear portion 10 ofeach of the brackets 8 extends on an even plane below the groove 9,ample clearance is provided to permit of the shifting of the guard rail13 without in terferin with the groove 9 formed on the lower e ge of thebracket 8.

When the guard rail 13 is in the extended position for use, as shown inFigure 1, ofthe drawing, the rear portion of the arms will rest in thegrooves 9, of respective brackets 8, and hold the guard rail 13 in thehorizontal position, as illustrated in the figure referred to.

When not in use, the guard rail 13, may be folded upwardly so that thearms thereof will extend parallel with respective vertical side members4 and 5 of the window frame. While in this position the ends of the armsof the guard rail 13 will extend in the depressed rear portions 10 ofthe brackets 8, the offset ro ecting portions of the brackets 8preventing liability of the guard rail 13 falling b gravity from suchfolded position, as t e guard rail springs into place by its frictiionahengagement with the brackets 8 during thefoiding operation.

A platform 15 for use in Connection with the guard rail 13 is providedand is supported by a pair of transversely disposed bars 16, havingtheir rear ends formed to provide hooks 17 adapted to engage the sill 6of the window frame. The forward ends of the bars 16 are pivoted. as at17, to the vertical guard bars 18 by means of the elongated rod 19. Theupper ends of the guard bars 18 are connected by anelongated rod 20.

A plurality of hangers 21 connects the platform 15 with the guard rail13. The lower ends of each of the hangers 21 is piv otally connected, asat 22. to therod 1S, and the upper ends of the halnlgers 21 are formedto provide hooks 28 adapted to cletachahly engage the guard rail 13. Therod 2) is riveted to the hangers 21.

A guard 24. preferably constructed from wire mesh, is carried by therods 18 and 2H. and covers the entire space therebetween.

The platform 15 and guard 24 may be flatly folded together when not inuse as clearly illustrated in Figure 4, of the d'rawin The firackets 8and guard rail 13 are intended to be permanently fixed to the win dowframe, but the platform 15 with associated parts is adapted to bedetachably connected therewith, to permit of its use with any windowsprovided with my improved guard rail 13.

The position of the guard rail 13, relatively to the window fr may beVaried to best meet conditions found'in practice.

By the use of my improved safety device persons engaged on windows at aheight may conveniently work and move about without the danger usuallyattending such operations.

What I claim is 2- 1. A safety device for the purpose set forthcomprising the combination with a window frame, of a pair of supportingbrackets carried by said window frame, and a guard rail pivotallyconnected to said brackets, said brackets having their rear portionsoffset adapted for the reception of said guard rail for securing saidguard rail in the inoperative or collapsed position.

2. A safety device for the purpose set forth comprising the combinationwith a window frame, of a pair of supporting brackets carried by saidwindow frame. a guard rail pivotally connected to said brackets. saidbrackets including means for securing said guard rail in the inoperativeposition, and a platform including a guard detachably connected withsaid window frame and with said guard rail.

3. A safety device for the purpose set forth comprising the combinationwith a window frame, of a pair of supporting brackets carried by saidwindow frame, a guard rail pivotally connected to said brackets, saidbrackets having their rear portions offset adapted for the reception ofsaid guard rail for securing said guard rail in the inoperative orcollapsed )osition, and a platform including a guard detachablyconnected with said window frame and with said guard rail.

4. A. safety device for the purpose set forth comprising the combinationwith a window frame, of a pair of triangularly shaped supportingbrackets carried by said frame. a substantially U shaped guard railhaving its arms pivotally connected with said brackets, each of saidbrackets having. a portion of its lower edge formed to provide groovesadapted for the reception of said guard rail arms for securing the said"guard rail in the extended or operative sition, said brackets furtherformed with depressed rear portions adapted for the reception of theguard rail arms for securing the guard rail in the collapsed orinoperativc. position, and a collapsible platform in cluding a guardelementpivotally connected with said platform. adapted to be dctachablyconnected to said window Frame and with said guard rail.

In testimony whereof I atiix my signature.
